Abstract (en)

[origin: EP3828888A1] The disclosure relates to a method for recognizing at least one naturally emitted sound produced by a real-life sound source in an environment comprising at least one artificial sound source (ASSr). The method is implemented by an audio recognition device, and it includes simultaneously obtaining (11) a first audio signal from a first microphone (MIC) located in the environment and a second audio signal from an audio acquisition device (AAD) associated with the at least one artificial sound source; analyzing (12) the first audio signal, delivering a first list of sound classes (L1) corresponding to sounds recognized in the first audio signal; analyzing (13) the second audio signal, delivering a second list of sound classes (L2) corresponding to sounds recognized in the second audio signal; and delivering (14) a third list of sound classes (L3), comprising only sound classes included in the first list of sound classes (L1) which are not included in the second list of sound classes (L2).
